Sound designer actually designs the sound from scratch (think Foley work in movies),
sound editor, audio engineer,and mixing engineer are all interchangeable but engineer is the broader term
There’s live sound and in studio.
Live sound – responsible for FOH (Front of house) makes sure all levels are correct, delay compensation, sound check, live auto tune, etc etc
In studio is a more controlled environment so you gotta set up mics, troubleshoot, patch, as well as everything a sound editor does
